Activists have walked out of U.N. climate talks the day before they end, saying two weeks of negotiations have brought no results

Wearing "Polluters talk, we walk" t-shirts, hundreds of activists walked out on Thursday from Warsaw's National Stadium, the venue for the meeting.

No deal is expected at talks, but they are meant to lay the foundation for a new agreement on greenhouse gas emission cuts in 2015.

Rich and poor nations are struggling with a yawning rift over developing countries' efforts to make developed countries accept responsibility for global warming.

Susann Scherbarth, from the Friends of the Earth Europe, says the walkout was held "out of frustration and disappointment" with the course of the talks.

The next round is next year in Lima, Peru.
